A laboratory has installed a double-suction, three-stage, centrifugalpump with a discharge of 330 gpm under 200 ft head and running at 1200 rpm. It isproposed to install another pump with double suction and six stages, but of the samecharacteristics, to operate at 98 ft head and deliver 430 gpm. Calculate a) the speed ofthe proposed pump; b) the impeller diameter of the proposed pump if the diameter of theexisting pump is 6 inches; and c) the type of the existing and the proposed pump.

A plant has installed a single suction centrifugal pump with a discharge of 68 m3/hr under 60 m head and running at 1200 rpm. It is proposed to install another pump with double suction but of the same type to operate at 30 m head`and deliver 90 m3/hr. What must be the impeller diameter of the proposed pump if the diameter of the existing pump is 150 mm?
A 5-m self-propelled combine makes an average stop of 4 min every time its 2-ton grain tank is to be unloaded. Gross yield of the 20-ha field is 42 tons. The operating speed is 4.8 kph.

A turbine is installed between reservoirs A and B whose difference in water surface elevation is 140m. The pipe connecting the reservoir has a diameter of 250mm and is 180m long. The flow of water is 180L/s. Use Hazen William's Formula with C1=100. What is the head extracted by the turbine?
Two reservoirs (EI 37.6m and EI 91.6m) are connected by two pipelines 1-2 and 2-3 with a pump bridging the two pipelines. If the fluid (sg=0.81) flows at a rate of 203 L/s, what is the power given by pump? Assume head losses of 2.3 j/n from 1-2 and 6.5 j/n from 2 to 3
Read the question carefully and give me right solution with clear calculations. Note: If you don't know the solution please leave it but don't give me wrong solution. At a river a suitable site for a run-of-the river installation has an available head of 13 m between the water intake and the turbine house. Environmental guidelines permit to extract water for hydropower only if it is in excess of 2.8 m3/s. Estimate the power generated in kW when the flow in the river is 10.9 m3/s for a turbine with an efficiency of 90%. Present the answer as integer in kW.
